For ideal solution, Δ Hsolution =Δ H1 +Δ H2+Δ H3

Q. Formation of a solution from two components can be considered as
(1) pure solvent $\to$ separated solvent molecules, $Δ H_{1}$
(2) pure solute $\to$ separated solute molecules, $Δ H_{2}$
(3) separated solvent and solute molecules $\to$ solution, $Δ H_{3}$
Solution so formed will be ideal if

$Δ H_{so l n} = Δ H_{1} - Δ H_{2} - Δ H_{3}$

$Δ H_{so l n} = Δ H_{3} - Δ H_{1} - Δ H_{2}$

$Δ H_{so l n} = Δ H_{1} + Δ H_{2} + Δ H_{3}$

$Δ H_{so l n} = Δ H_{1} + Δ H_{2} - Δ H_{3}$

For ideal solution,
$Δ H_{so l u t i o n} = Δ H_{1} + Δ H_{2} + Δ H_{3}$

Q. Formation of a solution from two components can be considered as (1) pure solvent → separated solvent molecules, ΔH1​ (2) pure solute → separated solute molecules, ΔH2​ (3) separated solvent and solute molecules → solution, ΔH3​ Solution so formed will be ideal if

ΔHsoln​=ΔH1​−ΔH2​−ΔH3​

ΔHsoln​=ΔH3​−ΔH1​−ΔH2​

ΔHsoln​=ΔH1​+ΔH2​+ΔH3​

ΔHsoln​=ΔH1​+ΔH2​−ΔH3​
